A week from today is our first day in Barcelona. We will be there for 3 full days leaving mid day on Monday. Forecast for Sunday is 60% chance of rain. Some of the areas of interest are: Guell Park, Sagrada Familia, La Rambles, La Boqueria Market, Picasso Museum, and seeing many of the neighborhoods. Would the best plan be to visit the cathedrals and museums on the rainy Sunday? Any other suggestions on how to spend a rainy day in Barcelona?

The Cathedrals, Boqueria and museums are all good for a wet day. The obvious outdoor places won't be. See if you can get a tour at the Palau de Musica Catalana, it's a stunning place and a great way to pass a couple of hours. Nice café too!

Understand that 60% chance of rain means there is a 60% chance of some rain, at some point during that 24 hours. So you could be rained out, have a shower or see no rain at all. Forecasts for Monday will not be accurate now. On Sunday maybe, but not now.

In terms of "visiting" Las Ramblas, you can do that at almost any time of day or evening. The "living statues" will be all over the place, especially on weekends, and the thoroughfare stays busy until quite late at night. I would not do it if it is raining.

Some rain is normal in the winter and spring. Currently, the weather on the 21st in Barcelona calls for sun, with a 20% change of rain the next day. Hardly worth worrying about. Just carry an umbrella like everyone else

We've been in Andalucia the last two weeks with only one evening of some measurable rainfall while Barcelona's been fair and dry with some clouds. Nothing unusual.

Perhaps plan the key destinations for the first and second clear days: Parc de Montjuic with the Miro museum, and Guell Park. Kind of opposite ends of the city, but shoot for one or the other as the views are great. The Picasso, the Gaudi houses, Segrada Familia are all fine for less than sunny weather; I'd try to do the Ramblas in a dry day too to absorb more local color. We only had one rainy day amidst 4 days in April and spent that in the Gothic quarter & the Picasso.

Remember that you can no longer just wander over to Guell Park. You have to purchase a ticket in advance (www.parkguell.cat/en/)

"Tickets can be purchased up to three months before the visit, choosing the date and time-band, up to a maximum of 9 tickets per person for each purchase.

Access to the Monumental Zone of Park Güell is limited to 400 tickets every half hour. For this reason we would recommend advance purchase of tickets through this website: that entitles you to visit the most iconic parts of the Park at the reserved times and lets you go directly to the entrance checking point if you have a printed ticket or have the QR code on your smartphone or tablet."

I think it's like any place -- if it's raining, you do things inside, such as shopping or museums. It's always rained whenever I've been in Barcelona, it rained several hours heavily the last time I was there last July, on a couple days. It was raining so hard at one point that I didn't even want to walk around in it with an umbrella, so I was stuck in a shopping mall. Not a very good one, though. I think another time it was raining I spent a couple hours in the Maritime museum down near the pier, and maybe the aquarium.

Rain forecast for Sunday in Barcelona is 100% rain. If we visit Sagrada Familia on Sunday, should we not purchase the tickets for the towers. On the website, it states that the towers may close due to rain and/or wind. Would it be best to plan the visit for a day with little to no rain?
